I meant that marriage doesn’t save a person from himself (meant to be gender neutral, not specifically referring to boys). If he is not mature enough to get married, it’s not as if getting married will suddenly make him ready to handle the challenges of marriage.
I was just at a speech by a shadchan, and she said that a 22-year-old boy came over to his mother and told her that he was ready to start dating. She said to him, “Let me ask you something. Let’s say you get married, and your wife becomes expecting right away. The baby is born with many physical/mental problems. Are you ready to handle that, to support your wife, and to deal with the challenges that this poses?” The boy said no. A year later, he came back to his mother and said, “Now I’m ready to get married.”
Do you think that the average boy in his early 20s is ready to handle that type of challenge? For that matter, do you think most 19-20 year old girls are? But no one thinks about that before they get married.
